My invention relates to freight car construction and more particularly to a ventilating ystem' which will allow circulation for heatingand coolin I .One of the objects of my invention is to provide an improved false floor construci tion, which can be easilygotten loutof the will be durable and efficientple in construction.

A further object of my invention is to provide a ventilated floor construction which Further objectswill appear'from the detailed'description to follow and-from the appended claims. 1 v

The refrigerator car 'construct1on shown a section :on the-line '7'7 of in the drawings comprises in a general way the car proper, comprising the main floor 10, the side walls-11, the roof 12, the end compartment 13 "for the ice 14 or heating device 1 5, and the double end wall 16, which provides'a passage for circulation at thev in use, and sim- The false floor 17 made six sections,

';the' floor-21,, 22 and 23 are identicalin con- 1 1 struction with the sections 18, 19 and 20 respectively. In Fig. 1 the sections 21 and 22 are shown swung up intofa vertical position; w

In order to swing the false floor 17 up .out of the way to get at the 'main fioor 10 for cleaning purposes or for sweeping out the car, the falsefioor sections 18, 20, 21 and 23 are hinged at their outside edges to the sides of the car so that these 1 sections can be swung up against the side of the car, and the sections 19 and 22 are hingedly connectedto thesections 18 and 21 respectively (Fig.

. plishes two purposes. First, it facilitates reagainst the side of thecar, section .1'9 can be moving the contents of the ear, and second,

it enables this sectionto'be folded out offlthe way of the door, so that-one can easily get into and out of the car after thefalse floor is folded up-out, of the Way. I c The f lse floor sections .are similar in' con- 'struction, comprising a plurality, of longitudinally extending stringers 32, which rest on the main fioor 10, when the false floor is end of the car, and in addition to the car The crosspieces 33 are spaced from, the

proper, a removable'fa1se'floor 17 is spaced from the main floor 10, to fprovideia circula- ,tion passage, so';that if, for instance,,the car is being used. in the winter, and the heat- I ing device 15 is used','the air can circulate, as 55 main floor 10 because of: thelongitudinally *extending stringers 32, so that free" ventilat-- in use, and a plurality of cross pieces'33 c which are secured to the stringers. 32.

,-ing passages are provided-from one end of --thecar*to the other, underneath the cross pieces 33 between the'stringers 32. The crossvpieces 33 are spaced from each other to permit' the circulating. air to pass up between 4 tions 19 and being shown in Figs. 6 and 7. v 10 these cross pieces and keep the'content s of the car atthe desired temperature.

Any suitable hinge connection may be Referring. in detail to the hinge connection between the section 18 and the side of the car 11 showing Figs. 4 and 5, this comprises a screw-eye 34, screwed into the side 1 of the car 11, and an eye-plate 35, secured to the false floor section 18, and pivotally connected with the screw-eye34. This construction permits the floor-section 18 to be thrown up against the side of" the car as indicated in Fig. 3.

' The hinge connection between the falsefloor section 18 and the short false floor section 19, shown in Figs. 6 and ,7 is such that the short floors'ection 19 can be swung in either direction about the adjacent edge of the longer floor section 18, for a purpose hereinafter. discussed. This hinge connec tion comprises a pair of eye-bolts .36 se- I my 1nvent1on,.1-t may be embodiedln other cured to the floor sectibns l8 and 19' respectively, and a short-chain 37 connecting the 3O tlwo eye-bolts 86.

As many of these connections as are necessary are provided for connecting the floor 1 sections 18 and 19, two such connections being shown in. the drawings as indicated at 38 and 39 in Fig. 1. -Also as 'manypoints of connection are provided between the floor-section 18 and the sideof the car 11,

maybe necessary, three being shown in the drawings as indicated at 40, a1 and 42.. As indicated above the short false floor section 19 is connected to the larger false floor section 18 insuch a waythat it can be swung in either direction about the edge of" the section 18, the chain 37,-.as shown in Fig. 7,

being made somewhat slack to permit this -movement'. This is desirable because when i removing the contents of the car, it is de swing this section in the other direction. The advantage of being able to swing the short sirable to. swing this section one direction,

and in folding up" the sections against, the

side of the car' after the 3 contents of the car have been removed, it is desirable to section 1911p oirt'of the way in cleaning out the car is thatflifthe contents ofthe car are such' that they have to, be removedbya scoop shovel, it is desirable to use the main 'floor lO as the scooping fioor, rather than the false floor 17. By having: the section 19. ,hingedly connected with. the section. 18, as

soon as the section 19 is cleared off in un loading thej'car, this section can be swung up topermit access .to' a part of the main raked'down onto this bare spot on the main 'fioor 10, and this bare spot can be used as a scooping floor. When the other short false floor section 22 is cleared ofi". it also can be swung up out of the way and additional scooping floor space gained; After the section 18. has-been cleared oif, the sections 18 and 19'can be gotten out of, the way by swinging the section 18 up against the side of the car, and then swinging the short sec- It will tion 19 up against the section 18. be noted that this latter movement of the short section 19 requires a movement in a direction opposite toy that which was required in swinging it up out of the way when the. false floor section 18 is in a horizontal position. As previously stated, the chain connection 37 permits this movement of the section 19 ineither direction.

' The manner in which the floor is used has been outlined'in connection with the description of the construction. After the contents of the catha'vebeen removed, the floor sections can all be swung up fiat against the side of car,so that the main floor 10- is exposed and accessible for cleaning.

While I have shown one embodiment of forms,-c overed and defined by the appended I" claim as new and desire to secure by Letters Patent of the United States is:
